China's 4D roller coaster

Thundering along at speeds of up to 126 kph, somersaulting through 720 degrees and plummeting almost vertically -- all in a little over two minutes -- “Dinoconda” may not be the fastest roller coaster in the world, but it’s certainly one of the scariest.

The RMB 200 million (US$31.6 million), 1,058-meter-long, 79-meter-high scream machine at China Dinosaur Land (中华恐龙园) outside Changzhou opened last April and is billed as China’s first "4D"roller coaster. The theme park is about 200 kilometers northwest of Shanghai.

Park officials say riders experience a "fourth dimension" aboard "Dinoconda" (过山龙), by being thrown upside-down in their seats which are mounted on the sides of the track and pivot independently from the track's orientation.
